Preliminaries

First we load some packages – two of them, concordances and collostructions, are not on CRAN and can therefore not be installed via install.packages. collostructions is available on Susanne Flach’s website, concordances is available on Github and can be installed using devtools::install_github (package devtools needs to be installed; if it is not installed yet, you can install it from CRAN.)

# install concordances package (if not yet installed)
if(!is.element("concordances", installed.packages())) {
  devtools::install_github("hartmast/concordances")
}

# load packages
library(collostructions) # available at sfla.ch
library(concordances)
library(tidyverse)
library(data.table)
library(ggraph)
library(igraph)
library(networkD3)
library(DT)
library(readxl)
library(vroom)
library(corrplot)

Queries

We used DECOW to search for quantifier/degree-modifier constructions. The following queries were used (followed by the number of matches):

# list of files
f <- list.files(pattern = "xml")

# get queries from concordance file:
sapply(1:length(f), function(i) trimws(gsub("<query>|</query>", "", readLines(f[i], n = 7)[6])))

Read in data

We use the concordances package to read in the data.

Data wrangling

We write and use a function to remove duplicates; we combine the concordances for “ein(e) X ADJ/N” and “ein(e) X zu ADJ”; and we add a lemma column to each concordance (using the automatic annotation).

# function for removing duplicates -----------
remove_duplicates <- function(df) {
  x <- which(duplicated(df$Left) && 
               duplicated(df$Key) &&
               duplicated(df$Right))
  
  if(length(x) > 0) {
    df <- df[-x,]
  }
  
  return(df)
  
}

# remove "unknown" lemma from "bisschen" dataframe
bisschen <- bisschen[grep("(unknown)", bisschen$Token, invert = T),]

# get modified nouns and adjectives in
# "bisschen" dataframe
bisschen$Lemma <- last_left(bisschen$Token, n = 1)

# remove empty column from bisschen
bisschen <- bisschen[,c(1,2,4)]

# backup copy
bisschen_backup <- bisschen

# some are duplicated, so we have to sum them up:
bisschen <- bisschen %>% group_by(Lemma) %>% summarise(
  Freq = sum(Freq)
)

# remove duplicates
idee <- remove_duplicates(idee)
tick <- remove_duplicates(tick)
handvoll <- remove_duplicates(handvoll)
tack_zack <- remove_duplicates(tack_zack)
fuenk <- remove_duplicates(fuenk)
hauch <- remove_duplicates(hauch)
spur <- remove_duplicates(spur)
idee_zu <- remove_duplicates(idee_zu)
tick_zu <- remove_duplicates(tick_zu)
tack_zack_zu <- remove_duplicates(tack_zack_zu)
fuenk_zu <- remove_duplicates(fuenk_zu)
hauch_zu <- remove_duplicates(hauch_zu)
spur_zu <- remove_duplicates(spur_zu)
quaentchen <- remove_duplicates(quaentchen)
quaentchen_zu <- remove_duplicates(quaentchen_zu)

# combine "zu" and "normal" ones:
idee <- rbind(mutate(idee), cxn_type = "ADJ_N",
      mutate(idee_zu), cxn_type = "zu_ADJ")
spur <- rbind(mutate(spur), cxn_type = "ADJ_N",
              mutate(spur_zu), cxn_type = "zu_ADJ")
fuenk <- rbind(mutate(fuenk), cxn_type = "ADJ_N",
              mutate(fuenk_zu), cxn_type = "zu_ADJ")
spur <- rbind(mutate(spur), cxn_type = "ADJ_N",
              mutate(spur_zu), cxn_type = "zu_ADJ")
tack_zack <- rbind(mutate(tack_zack), cxn_type = "ADJ_N",
              mutate(tack_zack_zu), cxn_type = "zu_ADJ")
tick <- rbind(mutate(tick), cxn_type = "ADJ_N",
              mutate(tick_zu), cxn_type = "zu_ADJ")
hauch <- rbind(mutate(hauch), cxn_type = "ADJ_N",
              mutate(hauch_zu), cxn_type = "zu_ADJ")
quaentchen <- rbind(mutate(quaentchen), cxn_type = "ADJ_N",
                    mutate(quaentchen_zu), cxn_type = "zu_ADJ")


# add lemma column
idee$Lemma <- last_left(idee, Tag3_Key, 1)
tick$Lemma <- last_left(tick, Tag3_Key, 1)
fuenk$Lemma <- last_left(fuenk, Tag3_Key, 1)
tack_zack$Lemma <- last_left(tack_zack, Tag3_Key, 1)
handvoll$Lemma <- last_left(handvoll, Tag3_Key, 1)
spur$Lemma <- last_left(spur, Tag3_Key, 1)
hauch$Lemma <- last_left(hauch, Tag3_Key, 1)
quaentchen$Lemma <- last_left(quaentchen, Tag3_Key, 1)

In the case of Idee, and to a lesser extent in the case of Hauch and Spur, there are still many false hits, so we export it for annotation…

# write_csv(idee, "idee_for_anno.csv")

# Hauch: add last_left of keyword
# hauch$Key_modified <- last_left(hauch$Key, n = 1, omit_punctuation = FALSE)

# spur$Key_modified <- last_left(spur$Key, n = 1, omit_punctuation = FALSE)

# write_csv(hauch, "hauch_for_anno.csv")
# write_csv(spur, "spur_for_anno.csv")

We re-import the annotated datafiles:

# import data
idee <- read_xlsx("idee_for_anno.xlsx")
hauch <- read_xlsx("hauch_for_anno.xlsx")
spur <- read_xlsx("spur_for_anno.xlsx")

# remove false hits
idee <- filter(idee, keep == "y")
hauch <- filter(hauch, Modifier == "y")
spur <- filter(spur, Modifier == "y")

As an intermediate step, we create a large dataframe containing all attestations together with more information about their source, taken from the DECOW document list.

# combine all:
d_all <- rbind(select(fuenk, c("Metatag1", "Left", "Key", "Right")),
      select(handvoll, c("Metatag1", "Left", "Key", "Right")),
      select(hauch, c("Metatag1", "Left", "Key", "Right")),
      select(idee, c("Metatag1", "Left", "Key", "Right")),
      select(quaentchen, c("Metatag1", "Left", "Key", "Right")),
      select(spur, c("Metatag1", "Left", "Key", "Right")),
      select(tack_zack, c("Metatag1", "Left", "Key", "Right")),
      select(tick, c("Metatag1", "Left", "Key", "Right")))

# list of DECOW documents
decowdoc <- vroom("/Volumes/My Passport/DECOW16BX-Corex/decow16b.doc.csv.gz", col_names = paste0("V", c(1:85)))

# only keep relevant columns
decowdoc <- decowdoc[,c(1:4)]

# join with d_all
d_all <- left_join(d_all, decowdoc, by = c("Metatag1" = "V4"))

# export
# write_excel_csv(d_all, "d_all.csv")
# re-import
# d_all <- read_csv("d_all.csv")

The full list is available here.

A cursory glance at the instances where the modified item is a verb shows that most if not all of them are false hits, hence we will exclude them from further analysis.

fuenk <- fuenk[grep("^V.*", last_left(fuenk$Tag2_Key, n = 1), invert = T),]
hauch <- hauch[grep("^V.*", last_left(hauch$Tag2_Key, n = 1), invert = T),]
tick <- tick[grep("^V.*", last_left(tick$Tag2_Key, n = 1), invert = T),]
quaentchen <- quaentchen[grep("^V.*", last_left(quaentchen$Tag2_Key, n = 1), invert = T),]
tack_zack <- tack_zack[grep("^V.*", last_left(tack_zack$Tag2_Key, n = 1), invert = T),]
tick <- tick[grep("^V.*", last_left(tick$Tag2_Key, n = 1), invert = T),]

Summary statistics

How often do the individual constructions combine with nouns and adjectives etc.?

# function for getting the distribution:
get_distro <- function(vec) {
  x <- gsub("(?<=.).*", "", last_left(trimws(vec), n = 1), perl = T) %>% table
  y <- x[which(names(x) %in% c("A", "N", "V"))]
  y <- c(y, "other" = sum(x[which(!names(x) %in% c("A", "N", "V"))]))
  return(y)
}

# function for finding comparatives:
get_compar <- function(df) {
  # find comparatives
  find_comparatives <- which(grepl("ADJ.*", last_left(df$Tag2_Key, n = 1)) &

  # add to df

}

  return(length(which(sapply(1:nrow(df), function(i) unlist(strsplit(df$Key[i], " "))[3])=="zu")))
}

# tabulate

We use the list of lemmas attested in the concordances to extract their total frequency in the DECOW corpus from the DECOW lemma frequency list.

# list of all lemmas across dfs
lemmas_all <- c(idee$Lemma, tick$Lemma, fuenk$Lemma, tack_zack$Lemma,
  handvoll$Lemma, bisschen$Lemma, spur$Lemma, hauch$Lemma, 
  quaentchen$Lemma) %>% unique


# collostructional analyses -----------------------------------------------
# 
# read DECOW lemma frequencies
decow <- fread("/Volumes/TOSHIBA EXT/DECOW ngrams/decow16bx.lp.tsv")

# only keep verbs, nouns and adjectives
decow01 <- decow[V2 %in% c("NN", "ADJD", "ADJA", "VAINF", "VVFIN", "VVINF", "VAPP", "VVPP", "VVIZU", "VAIMP")]
colnames(decow01) <- c("lemma", "pos", "Freq")

# count POS
pos_tbl <- decow01 %>% group_by(pos) %>% summarise(
  Freq = sum(Freq)
)

# only keep lemmas attested in the constructions
decow <- decow01[lemma %in% lemmas_all]

# export 
# saveRDS(decow, "decow_modifier_lemmas.Rds")
#saveRDS(pos_tbl, "pos_tbl.Rds")
# re-import
decow <- readRDS("decow_modifier_lemmas.Rds")
pos_tbl <- readRDS("pos_tbl.Rds")

Some of the lemmas in the decow dataframe occur more than once (e.g. because they have multiple POS tags), so we have to sum them up first. Also, the idee dataframe still contains many false hits, so we limit it to its most frequent domain by far, comparatives.

# sum up frequencies of lemmas occuring more than once
decow_sum <- decow %>% group_by(lemma) %>% summarise(
  Freq = sum(Freq)
)

Network analysis

The collexeme analysis is complemented by a network analysis. The aim of this analysis is to check whether different modified items combine with the modifiers to a similar degree or whether the items combining with the individual modifiers occupy certain semantic niches.

Number of shared collexemes

While the collexeme analyses give an impression of the semantics of each construction, another interesting question is how many of the collexemes are shared between the individual constructions. In order to assess this question, we create a word-construction-matrix and visualize it using a heatmap.

# create long list of lemmas and cxns
lemmas_df <- rbind(
  mutate(select(fuenk, Lemma), cxn = "Fünkchen"),
  mutate(select(hauch, Lemma), cxn = "Hauch"),
  mutate(select(handvoll, Lemma), cxn = "Handvoll"),
  mutate(select(idee, Lemma), cxn = "Idee"),
  mutate(select(quaentchen, Lemma), cxn = "Quäntchen"),
  mutate(select(spur, Lemma), cxn = "Spur"),
  mutate(select(tack_zack[grepl("Tacken", tack_zack$Key, ignore.case = T),], Lemma), cxn = "Tacken"),
  mutate(select(tack_zack[grepl("Zacken", tack_zack$Key, ignore.case = T),], Lemma), cxn = "Zacken"),
  mutate(select(tick, Lemma), cxn = "Tick"),
  mutate(select(bisschen, Lemma), cxn = "bisschen")
)

# find out how many items are shared between each 2 cxns
cxns <- unique(lemmas_df$cxn)

# empty dataframe
mydf <- data.frame(matrix(NA, nrow = 10, ncol = 10))
colnames(mydf) <- cxns
rownames(mydf) <- cxns

for(i in 1:length(cxns)) {
  for(j in 1:length(cxns)) {
    mydf[j,i] <- length(intersect(unique(filter(lemmas_df, cxn == colnames(mydf)[i])$Lemma),
          unique(filter(lemmas_df, cxn == rownames(mydf)[j])$Lemma)))
    
  }
}


# change to long dataframe
mydf2 <- rownames_to_column(mydf)
mydf_long <- pivot_longer(mydf2, 2:length(mydf2))
colnames(mydf_long) <- c("cxn_A", "cxn_B", "n")


# add columns "shared" and "non-shared" to visualize
mydf_long$shared <-sapply(1:nrow(mydf_long), function(i) length(intersect(unique(lemmas_df[which(lemmas_df$cxn==mydf_long$cxn_A[i]),]$Lemma),
unique(lemmas_df[which(lemmas_df$cxn==mydf_long$cxn_B[i]),]$Lemma)))
)

mydf_long$nonshared <- sapply(1:nrow(mydf_long), function(i) length(setdiff(unique(lemmas_df[which(lemmas_df$cxn==mydf_long$cxn_A[i]),]$Lemma),
unique(lemmas_df[which(lemmas_df$cxn==mydf_long$cxn_B[i]),]$Lemma)))
)

# select relevant columns
mydf_long2 <- mydf_long %>% select(cxn_A, cxn_B, shared, nonshared)

# add relative column
# relative to sum of shared and nonshared items:
mydf_long2$rel <- mydf_long2$shared / (mydf_long2$shared + mydf_long2$nonshared)

# absolute values with shared and sum total of items
mydf_long2$abs <- paste(mydf_long2$shared, "\n(", mydf_long2$nonshared + mydf_long2$shared, ")", sep = "")

# even better: paste it to x axis labels
mydf_long2$x <- paste(mydf_long2$cxn_A, " (", mydf_long2$nonshared + mydf_long2$shared, ")", sep="")

# heatmap
mydf_long2 %>% filter(rel < 1) %>% ggplot(aes(x = cxn_B, y = x, fill = rel, label = shared)) + geom_tile() + geom_text() + scale_fill_gradient(low = "yellow", high = "darkred") +
  xlab("Construction") + ylab("Construction") + 
  guides(fill = "none") + theme_classic() + theme(axis.text.x = element_text(angle=45, hjust=.9)) +     scale_y_discrete(limits=rev)

# ggsave("heatmap002_all_types.png", width = 7, height = 6)

# incl. shared with itself:
mydf_long2 %>% ggplot(aes(x = cxn_B, y = x, fill = rel, label = shared)) + geom_tile() + geom_text() + scale_fill_gradient(low = "yellow", high = "darkred") +

The same limited to the top 100 collexemes for each construction:
